　　YF318陽離子(zi)淀粉產品特性

　　characteristics of YF318 cationic starch

　　YF318漿內添(tian)加淀粉屬季(ji)銨型陽離(li)子(zi)淀粉.該淀粉在(zai)淀粉分子(zi)鏈(lian)上嫁接了較(jiao)多陽離(li)子(zi)基團(tuan),因(yin)而(er)在(zai)造紙漿料系(xi)統中,除(chu)能與纖維(wei)結合提高(gao)成(cheng)紙內聚力、抗張(zhang)強度、耐折次數等物理指標以外(wai),還同時對細小纖維(wei)和填料物質起到較(jiao)好的助留(liu)作用,因(yin)而(er)能明顯地降(jiang)低網下白水濃度,提高(gao)留(liu)著率(lv)并能有效地改善(shan)漿料的濾水性.有利于紙頁脫(tuo)水,提高(gao)車速.

　　YF318 pulp-add starch is a kind of quaternary ammonium cationic starch.It has been grafted many cationic groups on the molecule chains of the starch.Not only can it improve the paper physical index of cohesive force,tensile strength and folding strength,but also it will help to remain the fines and fillers,therefor it can obviously lower the consistency of white water,increase the retention and improve the drainability of the pulp effectively,so it will help paper dewatering and heighten the speed of the paper machine.
